Hlw mate here is your answer
In this lesson we learn to solve problems on speed, distance, time, relative speed and boats and streams etc
Key Concepts
1. Distance = Speed × Time
2. 1 km/hr = 518518 m/s
3. If the ratios of speed is a : b : c, then the ratios of time taken is : 1a:1b:1c1a:1b:1c
Relation between variables:
To distance, Speed and Time both are directly proportional and To speed, Time is inversely proportional. S∝DS∝D and T∝DT∝Di.e. if speed is doubled, distance covered in a given time also gets doubled and ,S∝1TS∝1Ti.e. if speed is doubled, time taken to cover a distance will be half.
Average speed is defined as =.Total distance travelledTotal time takenTotal distance travelledTotal time taken
Relative speed
If two bodies are moving (in the same direction or in the opposite direction), then the speed of one body with respect to the other is called its relative speed.
Relative speed is a phenomenon that we observe everyday. Suppose you are travelling in college bus and there is a second bus coming in the opposite direction, then it seems that the second Bus is moving much faster than actual. If both the Buses were moving in the same direction at same speeds, they seem to be stationary if seen from one of these Busses, even though they might actually be at a speed of 100 km/hr each. So what you actually observe is your speed relative to the other.
